Perfect as an additional upgrade a few months after my build. Needed to separate main drive from games so I don't have my previous SSD at more than 70% capacity and being an M.2 SSD, no extra cabling was required.

This actually came out of my 2015 Dell XPS 13 ultrabook. It was cheaper to buy a 128GB version and upgrade it later than it was to get higher capacity straight from Dell, and as a bonus I got a spare SSD to reuse in my desktop. It's a standard SATA B+M key drive and nothing special but it works very well as a Linux boot drive. The only problem is that some newer motherboards don't recognize the M.2 SATA standard and only accept M.2 PCIe and NVMe SSDs.
